Applicationflled March 23, 191G. Serial No. 552,009:

of trucks for railway vehicles, and is par-' ticularlydirected to such a combination and arrangement of arts as will permit bolsters of various dimensions to be employed with a single form of side-frame and will also permit the facile replacement of damaged truck-bolsters Without the necessity of dismantling the truck.

There are other, minor, objects of invention involving particular combinations and features of elemental construction, all as will hereinafter more fully appear.

In the drawings chosen forthe purpose of illustrating my invention, the scope whereof is pointed out in the claims, Figure 1 is a slde view of a car truck embodying my invention; Fig. 2 is a detail view of a portion of the truckillustrated in Fig. 1, the side frame being in horizontal section and the adjacent end of the bolster and associated parts being in plan; Fig. 3 .is a detail view of the construction shown in Fig. l, the bolster and associated parts being in elevation and the side frame being in vertical, central section; Fig. i is a detail perspective view of the combined side-bearing, bolster-guide and filler illustrated in the preceding views; Fig. 5 is a side eleva tion of a truck embodying a modified form of my invention; Fig. 6 .is a detail view taken in the plane of the line 6-6, Fig. 5; Fig. 7 is a detail side elevation of the sideframe and adjustable columns shown in Fig. 5, one of the columns bein shown in the'position it occupies when t e truck is assembled, and the other column being illustrated in the position itoccupies when the bolster is to be placed in positionor withdrawn; Fig.- 8 is a horizontal section taken in the plane of the line S-8, Fig. 7; Fig. 9 is a detail view of the construction illustrated in Fig. 5, showing the relation of the body bolster thereto, the bolster and associated parts being in elevation and the side-frame being in vertical central section; and- Fig. 10 is a detail perspective View of the combined side-bearing and bolster guide employed in the modified form of. my invention.

Like symbols refer to like parts wherever they occur.

i 1 will now roceed-to describe my invention more fui y, so that others skilled in the art to whichit appertains may apply the same.

Only one half of each-form of truck illustrated in the drawings will be described, since both sides of each truck structure are identical.

Inthe "construction illustrated in the drawings, 1 indicates the side frame shown in Figs. I told, inclusive, while 2- indicates the side frame of the modified form of construction showngin the remaining figures of the drawings. The journal boxes 3, which maybe of any well known or desired type, may be secured to the side frames in any suitable manner, journal-box bolts .4 such as are ordinarily employed being here illustrated. It will be understood, however, that the form of the journal-boxes and the man ner of their'application to the side frames is wholly immaterial so far as my present invention is concerned.

Generallyspeaking, any type of body I poses of illustration a bolster 5 which is of a type that is wider and deeper at its center than at its ends, since, hitherto constructed, trucks employing bolsters of such relative dimensions have had to be dismantled in order to remove and replace the bolster.

Each of the side frames 1 and 2 is formed with a centrally located bolster opening which exceeds in width and depth the greatest corresponding dimensions of the bolster employed therewith. T he ends of the bolster which project into these bolster openings rest upon bolster-springs 6 that transmit the load of the car body to the side-frames' In the form of construction illustrated in 1 to 4, inclusiye. the side-frame 1 is shown as formed with integrally connected, vertically extending columns 7 which border thesides of the bolsteropening and which are adapted to be slidably engaged by a bolster guide member 8 that is detachably se 9) to assist in maintaining the saddle 12 in cured to the outer end of the bolster 5.
